Star Wars: Raiders of the Lost Empires

The Yuuzahan Vong War

In 103ABY, the greatest disaster to have ever occured in Galactic history began: the Yuuzahan Vong invaded. Fleeing form the destruction of their own galaxy, the Yuuzahan Vong brought with them vast numbers of soldiers, and powerful biotechnology. Further more, they could not be affected with the Force.
The war had been centuries in the making; indeed, Yuuzhan Vong agents, scouts and advance fleets were present throughout the galaxy at least decades before the invasion was launched, undetected by all but a few. Emperor Palpatine himself, before his ascension to power at the head of the Galactic Empire, knew of the coming Yuuzhan Vong, and the imminent invasion was a primary motivation for his creation of the Imperial Starfleet and the regime which he installed upon the galaxy. It was not the Galactic Empire, however, but the fledgling New Republic and a galaxy shaken by a series of crises and civil wars, which met the colossal Yuuzhan Vong armada.
Suffice to say the Republic was completely unprepared for the attack and were overwhelmed at an extraordinary rate. Chief of State Borsk Fey’lya’s ill-prepared and inefficient government was unable to prevent the extra-galactic species from driving inexorably toward the Core. Coruscant, the galactic capital, was conquered and remade by the invaders two years after the invasion commenced; by this time, countless species were rendered extinct and entire planets uninhabitable. It was now every planet for itself as anarchy ensued.
Wracked with internal tensions as it was, the Yuuzhan Vong Empire was still able to neutralize many of the threats facing it, before going once more on the offensive. The New Republic, reformed under Alderaanian Chief of State Cal Omas into the Galactic Federation of Free Alliances, was brought to the brink of defeat, and moved toward the fatal deployment of Alpha Red, a pathogen hostile to the Yuuzhan Vong, in response to a renewed Yuuzhan Vong advance upon its temporary capital at Dac
The ploy was a success, but the Yuuzahan Vong were not the only species affected and a plague began to spread across the galaxy with few ever realising the true source until decades after the fact. In the end, it was enough to set the invaders on the back foot.
Zonama Sekot, a seed of the lost living homeworld of the Yuuzhan Vong, emerged over Coruscant, its arrival precipitating the final battle of the conflict in 115ABY. The Jedi Council itself, who had located Zonama Sekot and urged its return, defeated Warlord Shimrra Jamaane and the true master of the Yuuzhan Vong, Onimi, during a raid that cost them their lives, while fleets of warships clashed once more in space. The Yuuzhan Vong War ended with the deaths of the Supreme Overlord and the surrender of the remaining armada. The resulting Sekot Accords, which stipulated disarmament and amnesty for the Yuuzhan Vong, proved deeply unpopular for many.
